11.2 Oscillation controlled via synchronized actions

Programming example

No infeed is to take place at reversal point 1. At

reversal point 2, the infeed is to start at a distance of

ii2 before reversal point 2 and the oscillating axis is

not to wait at the reversal point for the end of the

partial infeed. Axis Z is the oscillating axis and axis X

the infeed axis.

Program extract

1. Define parameters for oscillation

OSP1[Z]=10 OSP2[Z]=60

OST1[Z]=0 OST2[Z]=0

FA[Z]=150 FA[X]=0.5

OSCTRL[Z]=(2+8+16,1)

Approach reversal point 1

and 3 sparking-out strokes

Define variable for reversal area 2

Define reversal points 1 and 2

Reversal point 1: exact stop fine

Reversal point 2: exact stop fine

Oscillating axis Z feedrate, infeed axis X

Deactivate oscillating motion at reversal

point 2; after delete DTG spark-out and

approach end position; after delete DTG

approach reversal position

3 spark-out strokes

End position = 70

Set reversal area

Enable oscillation for Z axis
